This application is a continuation of U.S. patent application Ser. No.16/947,472, filed on Aug. 3, 2020, entitled “TECHNIQUES FOR IN-BANDREPEATER CONTROL,” which claims priority to U.S. Provisional PatentApplication No. 62/882,959, filed on Aug. 5, 2019, entitled “TECHNIQUESFOR IN-BAND REPEATER CONTROL,” each of which are hereby expresslyincorporated by reference herein.

FIELD OF THE DISCLOSURE

Aspects of the present disclosure generally relate to wirelesscommunication and to techniques for in-band repeater control.

DESCRIPTION OF RELATED ART

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (e.g., bandwidth,transmit power, and/or the like). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A user equipment (UE) may communicate with a base station (BS)via the downlink and uplink. The downlink (or forward link) refers tothe communication link from the BS to the UE, and the uplink (or reverselink) refers to the communication link from the UE to the BS. As will bedescribed in more detail herein, a BS may be referred to as a Node B, agNB, an access point (AP), a radio head, a transmit receive point (TRP),a New Radio (NR) BS, a 5G Node B, and/or the like.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. New Radio (NR), which may also bereferred to as 5G, is a set of enhancements to the LTE mobile standardpromulgated by the Third Generation Partnership Project (3GPP). NR isdesigned to better support mobile broadband Internet access by improvingspectral efficiency, lowering costs, improving services, making use ofnew spectrum, and better integrating with other open standards usingorthogonal frequency division multiplexing (OFDM) with a cyclic prefix(CP) (CP-OFDM) on the downlink (DL), using CP-OFDM and/or SC-FDM (e.g.,also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) onthe uplink (UL), as well as supporting beamforming, multiple-inputmultiple-output (MIMO) antenna technology, and carrier aggregation.However, as the demand for mobile broadband access continues toincrease, there exists a need for further improvements in LTE and NRtechnologies. Preferably, these improvements should be applicable toother multiple access technologies and the telecommunication standardsthat employ these technologies.

Various aspects of the disclosure are described more fully hereinafterwith reference to the accompanying drawings. This disclosure may,however, be embodied in many different forms and should not be construedas limited to any specific structure or function presented throughoutthis disclosure. Rather, these aspects are provided so that thisdisclosure will be thorough and complete, and will fully convey thescope of the disclosure to those skilled in the art. Based on theteachings herein one skilled in the art should appreciate that the scopeof the disclosure is intended to cover any aspect of the disclosuredisclosed herein, whether implemented independently of or combined withany other aspect of the disclosure. For example, an apparatus may beimplemented or a method may be practiced using any number of the aspectsset forth herein. In addition, the scope of the disclosure is intendedto cover such an apparatus or method which is practiced using otherstructure, functionality, or structure and functionality in addition toor other than the various aspects of the disclosure set forth herein. Itshould be understood that any aspect of the disclosure disclosed hereinmay be embodied by one or more elements of a claim.

Several aspects of telecommunication systems will now be presented withreference to various apparatuses and techniques. These apparatuses andtechniques will be described in the following detailed description andillustrated in the accompanying drawings by various blocks, modules,components, circuits, steps, processes, algorithms, and/or the like(collectively referred to as “elements”). These elements may beimplemented using hardware, software, or combinations thereof. Whethersuch elements are implemented as hardware or software depends upon theparticular application and design constraints imposed on the overallsystem.

FIG. 1 is a diagram illustrating a wireless network 100 in which aspectsof the present disclosure may be practiced. The wireless network 100 maybe an LTE network or some other wireless network, such as a 5G or NRnetwork. The wireless network 100 may include a number of BSs 110 (shownas BS 110 a, BS 110 b, BS 110 c, and BS 110 d) and other networkentities. A BS is an entity that communicates with user equipment (UEs)and may also be referred to as a base station, a NR BS, a Node B, a gNB,a 5G node B (NB), an access point, a transmit receive point (TRP),and/or the like. Each BS may provide communication coverage for aparticular geographic area. In 3GPP, the term “cell” can refer to acoverage area of a BS and/or a BS subsystem serving this coverage area,depending on the context in which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, and/or another type of cell. A macro cell may cover arelatively large geographic area (e.g., several kilometers in radius)and may allow unrestricted access by UEs with service subscription. Apico cell may cover a relatively small geographic area and may allowunrestricted access by UEs with service subscription. A femto cell maycover a relatively small geographic area (e.g., a home) and may allowrestricted access by UEs having association with the femto cell (e.g.,UEs in a closed subscriber group (CSG)). A BS for a macro cell may bereferred to as a macro BS. A BS for a pico cell may be referred to as apico BS. A BS for a femto cell may be referred to as a femto BS or ahome BS. In the example shown in FIG. 1 , a BS 110 a may be a macro BSfor a macro cell 102 a, a BS 110 b may be a pico BS for a pico cell 102b, and a BS 110 c may be a femto BS for a femto cell 102 c. ABS maysupport one or multiple (e.g., three) cells. The terms “eNB”, “basestation”, “NR BS”, “gNB”, “TRP”, “AP”, “node B”, “5G NB”, and “cell” maybe used interchangeably herein.

In some aspects, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some aspects, the BSs may be interconnected to one anotherand/or to one or more other BSs or network nodes (not shown) in thewireless network 100 through various types of backhaul interfaces suchas a direct physical connection, a virtual network, and/or the likeusing any suitable transport network.

Wireless network 100 may also include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (e.g., a BS or a UE) and send a transmission of the data to adownstream station (e.g., a UE or a BS). A relay station may also be aUE that can relay transmissions for other UEs. In the example shown inFIG. 1 , a relay station 110 d may communicate with macro BS 110 a and aUE 120 d in order to facilitate communication between BS 110 a and UE120 d. A relay station may also be referred to as a relay BS, a relaybase station, a relay, and/or the like.

Wireless network 100 may be a heterogeneous network that includes BSs ofdifferent types, e.g., macro BSs, pico BSs, femto BSs, relay BSs, and/orthe like. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein wireless network 100. For example, macro BSs may have a high transmitpower level (e.g., 5 to 40 watts) whereas pico BSs, femto BSs, and relayBSs may have lower transmit power levels (e.g., 0.1 to 2 watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. Network controller 130 maycommunicate with the BSs via a backhaul. The BSs may also communicatewith one another, e.g., directly or indirectly via a wireless orwireline backhaul.

UEs 120 (e.g., 120 a, 120 b, 120 c) may be dispersed throughout wirelessnetwork 100, and each UE may be stationary or mobile. A UE may also bereferred to as an access terminal, a terminal, a mobile station, asubscriber unit, a station, and/or the like. A UE may be a cellularphone (e.g., a smart phone), a personal digital assistant (PDA), awireless modem, a wireless communication device, a handheld device, alaptop computer, a cordless phone, a wireless local loop (WLL) station,a tablet, a camera, a gaming device, a netbook, a smartbook, anultrabook, a medical device or equipment, biometric sensors/devices,wearable devices (smart watches, smart clothing, smart glasses, smartwrist bands, smart jewelry (e.g., smart ring, smart bracelet)), anentertainment device (e.g., a music or video device, or a satelliteradio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, location tags, and/or the like, that may communicate with abase station, another device (e.g., remote device), or some otherentity. A wireless node may provide, for example, connectivity for or toa network (e.g., a wide area network such as Internet or a cellularnetwork) via a wired or wireless communication link. Some UEs may beconsidered Internet-of-Things (IoT) devices, and/or may be implementedas NB-IoT (narrowband internet of things) devices. Some UEs may beconsidered a Customer Premises Equipment (CPE). UE 120 may be includedinside a housing that houses components of UE 120, such as processorcomponents, memory components, and/or the like.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular radioaccess technology (RAT) and may operate on one or more frequencies. ARAT may also be referred to as a radio technology, an air interface,and/or the like. A frequency may also be referred to as a carrier, afrequency channel, and/or the like. Each frequency may support a singleRAT in a given geographic area in order to avoid interference betweenwireless networks of different RATs. In some cases, NR or 5G RATnetworks may be deployed.

In some aspects, two or more UEs 120 (e.g., shown as UE 120 a and UE 120e) may communicate directly using one or more sidelink channels (e.g.,without using a base station 110 as an intermediary to communicate withone another). For example, the UEs 120 may communicate usingpeer-to-peer (P2P) communications, device-to-device (D2D)communications, a vehicle-to-everything (V2X) protocol (e.g., which mayinclude a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure(V2I) protocol, and/or the like), a mesh network, and/or the like. Inthis case, the UE 120 may perform scheduling operations, resourceselection operations, and/or other operations described elsewhere hereinas being performed by the base station 110.

In some aspects, a repeater 140 may receive a radio frequency (RF)analog signal (e.g., an analog millimeter wave signal) from a basestation 110, may amplify the RF analog signal, and may transmit theamplified RF signal to one or more UEs 120 (e.g., shown as UE 120 f). Insome aspects, the repeater 140 may be an analog millimeter wave (mmW)repeater, sometimes also referred to as a layer 1 mmW repeater.Additionally, or alternatively, the repeater 140 may be a wirelesstransmit receive point (TRP) acting as a distributed unit (e.g., of a 5Gaccess node) that communicates wirelessly with a base station 110 actingas a central unit or an access node controller (e.g., of the 5G accessnode). The repeater 140 may receive, amplify, and transmit an RF analogsignal without performing analog-to-digital conversion of the RF analogsignal and/or without performing any digital signal processing on the RFanalog signal. In this way, latency may be reduced and a cost to producethe repeater 140 may be reduced. Additional details regarding repeater140 are provided elsewhere herein.

As indicated above, FIG. 1 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 1 .

FIG. 2 shows a block diagram of a design 200 of base station 110 and UE120, which may be one of the base stations and one of the UEs in FIG. 1. Base station 110 may be equipped with T antennas 234 a through 234 t,and UE 120 may be equipped with R antennas 252 a through 252 r, where ingeneral T≥1 and R≤1.

At base station 110, a transmit processor 220 may receive data from adata source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (e.g., encodeand modulate) the data for each UE based at least in part on the MCS(s)selected for the UE, and provide data symbols for all UEs. Transmitprocessor 220 may also process system information (e.g., for semi-staticresource partitioning information (SRPI) and/or the like) and controlinformation (e.g., CQI requests, grants, upper layer signaling, and/orthe like) and provide overhead symbols and control symbols. Transmitprocessor 220 may also generate reference symbols for reference signals(e.g., the cell-specific reference signal (CRS)) and synchronizationsignals (e.g., the primary synchronization signal (PSS) and secondarysynchronization signal (SSS)). A transmit (TX) multiple-inputmultiple-output (MIMO) processor 230 may perform spatial processing(e.g., precoding) on the data symbols, the control symbols, the overheadsymbols, and/or the reference symbols, if applicable, and may provide Toutput symbol streams to T modulators (MODs) 232 a through 232 t. Eachmodulator 232 may process a respective output symbol stream (e.g., forOFDM and/or the like) to obtain an output sample stream. Each modulator232 may further process (e.g., convert to analog, amplify, filter, andupconvert) the output sample stream to obtain a downlink signal. Tdownlink signals from modulators 232 a through 232 t may be transmittedvia T antennas 234 a through 234 t, respectively to UE 120, repeater140, and/or the like. According to various aspects described in moredetail below, the synchronization signals can be generated with locationencoding to convey additional information.

At UE 120, antennas 252 a through 252 r may receive the downlink signalsfrom base station 110, repeater 140, and/or other wireless communicationdevices and may provide received signals to demodulators (DEMODs) 254 athrough 254 r, respectively. Each demodulator 254 may condition (e.g.,filter, amplify, downconvert, and digitize) a received signal to obtaininput samples. Each demodulator 254 may further process the inputsamples (e.g., for OFDM and/or the like) to obtain received symbols. AMIMO detector 256 may obtain received symbols from all R demodulators254 a through 254 r, perform MIMO detection on the received symbols ifapplicable, and provide detected symbols. A receive processor 258 mayprocess (e.g., demodulate and decode) the detected symbols, providedecoded data for UE 120 to a data sink 260, and provide decoded controlinformation and system information to a controller/processor 280. Achannel processor may determine reference signal received power (RSRP),received signal strength indicator (RSSI), reference signal receivedquality (RSRQ), channel quality indicator (CQI), and/or the like. Insome aspects, one or more components of UE 120 may be included in ahousing.

On the uplink, at UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (e.g., forreports comprising RSRP, RSSI, RSRQ, CQI, and/or the like) fromcontroller/processor 280. Transmit processor 264 may also generatereference symbols for one or more reference signals. The symbols fromtransmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by modulators 254 a through 254 r (e.g.,for DFT-s-OFDM, CP-OFDM, and/or the like), and transmitted to basestation 110 and/or to repeater 140. At base station 110, the uplinksignals from UE 120, the repeater 140, and/or other wirelesscommunication devices may be received by antennas 234, processed bydemodulators 232, detected by a MIMO detector 236 if applicable, andfurther processed by a receive processor 238 to obtain decoded data andcontrol information sent by UE 120. Receive processor 238 may providethe decoded data to a data sink 239 and the decoded control informationto controller/processor 240. Base station 110 may include communicationunit 244 and communicate to network controller 130 via communicationunit 244. Network controller 130 may include communication unit 294,controller/processor 290, and memory 292.

Controller/processor 240 of base station 110, controller/processor 280of UE 120, and/or any other component(s) of FIG. 2 may perform one ormore techniques associated with in-band repeater control, as describedin more detail elsewhere herein. For example, controller/processor 240of base station 110, controller/processor 280 of UE 120, and/or anyother component(s) of FIG. 2 may perform or direct operations of, forexample, process 700 of FIG. 7 and/or other processes as describedherein. Memories 242 and 282 may store data and program codes for basestation 110 and UE 120, respectively. In some aspects, memory 242 and/ormemory 282 may comprise a non-transitory computer-readable mediumstoring one or more instructions for wireless communication. Forexample, the one or more instructions, when executed by one or moreprocessors of the base station 110 and/or the UE 120, may perform ordirect operations of, for example, process 700 of FIG. 7 and/or otherprocesses as described herein. A scheduler 246 may schedule UEs for datatransmission on the downlink and/or uplink.

In some aspects, UE 120 may include means for transmitting uplinkcommunications to a BS 110 via a repeater 140, means for receivingdownlink communications from the BS 110 via the repeater 140, and/or thelike. In some aspects, such means may include one or more components ofUE 120 described in connection with FIG. 2 , such ascontroller/processor 280, transmit processor 264, TX MIMO processor 266,MOD 254, antenna 252, DEMOD 254, MIMO detector 256, receive processor258, and/or the like.

In some aspects, base station 110 may include means for configuring oneor more repeater configurations for a repeater 140, means fortransmitting an indication of the one or more repeater configurations tothe repeater 140 in a bandwidth part (BWP) that carries a controlinterface of the repeater 140, means for transmitting downlinkcommunications to a UE 120 via the repeater 140, means for receiving oneor more uplink communications from the UE 120 via the repeater 140,and/or the like.

As indicated above, FIG. 2 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 2 .

FIG. 3 is a diagram illustrating an example of a repeater 300, inaccordance with various aspects of the present disclosure. In someaspects, repeater 300 may correspond to repeater 140 shown in FIG. 1 .In some aspects, repeater 300 may be a millimeter wave repeater thatcommunicates via millimeter wave transmissions (e.g., as opposed tosub-6 GHz transmissions).

As shown in FIG. 3 , repeater 300 may include one or more antenna arrays(or antennas, antenna panels, and/or the like) 310-1 through 310-N(N>1), a gain component 320, a controller 330, a communication component340, and a multiplexer (MUX) 350 a and/or demultiplexer (DEMUR) 350 b(collectively referred to as a MUX/DEMUX 350.

An antenna array 310 may include multiple antenna elements capable ofbeing configured for beamforming. For example, an antenna array 310 maybe referred to as a phased array because phase values and/or phaseoffsets of the antenna elements may be configured to form a beam, withdifferent phase values and/or phase offsets being used for differentbeams (e.g., in different directions). In some aspects, an antenna array310 may be a fixed receive (Rx) antenna array capable of only receivingcommunications while not transmitting communications. In some aspects,an antenna array 310 may be a fixed transmit (Tx) antenna array capableof only transmitting communications while not receiving communications.In some aspects, an antenna array 310 may be configured to act as an Rxantenna array or a Tx antenna array (e.g., via a Tx/Rx switch, aMUX/DEMUX, and/or the like). An antenna array 310 may be capable ofcommunicating using millimeter waves and/or other types of RF analogsignals.

Gain component 320 includes one or more components capable of amplifyingan input signal and outputting an amplified signal. For example, gaincomponent 320 may include a power amplifier, a variable gain component,and/or the like. In some aspects, gain component 320 may have variablegain control. Gain component 320 may connect to an Rx antenna array(e.g., a first antenna array 310-1) and a Tx antenna array (e.g., asecond antenna array 310-2) such that an RF analog signal, received viathe Rx antenna array, can be amplified by gain component 320 and outputto the Tx antenna array for transmission. In some aspects, the level ofamplification of gain component 320 may be controlled by the controller330.

Controller 330 includes one or more components capable of controllingone or more other components of repeater 300. For example, controller330 may include a controller, a microcontroller, a processor, and/or thelike. In some aspects, controller 330 may control gain component 320 bycontrolling a level of amplification or gain applied by gain component320 to an input signal. Additionally, or alternatively, controller 330may control an antenna array 310 by controlling a beamformingconfiguration for the antenna array 310 (e.g., one or more phase valuesfor the antenna array 310, one or more phase offsets for the antennaarray 310, one or more power parameters for the antenna array 310, oneor more beamforming parameters for the antenna array 310, a Txbeamforming configuration, an Rx beamforming configuration, and/or thelike), by controlling whether the antenna array 310 acts as an Rxantenna array or a Tx antenna array (e.g., by configuring interactionand/or connections between the antenna array 310 and a MUX/DEMUX 350),and/or the like. Additionally, or alternatively, controller 330 maypower on or power off one or more components of repeater 300 (e.g., whena BS 110 does not need to use the repeater to serve UEs 120). In someaspects, controller 330 may control a timing of one or more of the aboveconfigurations.

Additionally, or alternatively, controller 330 may control a position ofa switch 380, included in repeater 300, in order to cause an oscillator360, included in repeater 300, to be connected to one or more antennas310 (e.g., via another gain component 370 included in repeater 300) inassociation with transmitting an RF analog signal. In some aspects,controller 330 may control gain component 370 by controlling a level ofamplification or gain applied by gain component 370 to a signal providedby oscillator 360.

Communication component 340 may include a component capable ofwirelessly communicating with a BS 110 via a control interface. In someaspects, communication component 340 may communicate with the BS 110using one or more in-band radio frequencies (e.g., radio frequenciesthat are included within an operating frequency bandwidth of antennaarrays 310-1 through 310-N). In this case, the BS 110 may configure aBWP within the operating frequency bandwidth of antenna arrays 310-1through 310-N (e.g., an in-band BWP) such that the BWP carries thecontrol interface associated with repeater 300. In some aspects, anantenna array 310 may be used to wirelessly forward (e.g., transmitand/or receive) RF analog signals between repeater 300 and the BS 110,between repeater 300 and one or more UEs 120, and/or the like, andcommunication component 340 may be used to transfer control informationbetween repeater 300 and the BS 110.

In some aspects, communication component 340 may include one or morecomponents for digital signal processing (e.g., digital signalprocessor, a baseband processor, a digital-to-analog converter (DAC), ananalog-to-digital converter (ADC), and/or the like). In this way,communication component 340 may demodulate, decode, and/or perform othertypes of processing on the control information received from a BS 110.

MUX/DEMUX 350 may be used to multiplex and/or demultiplex communicationsreceived from and/or transmitted to an antenna array 310. For example,MUX/DEMUX 350 may be used to switch an Rx antenna array to a Tx antennaarray.

Oscillator 360 may be used to generate an RF analog signal fortransmission by repeater 300 via an antenna array 310. Gain component370 includes one or more components capable of amplifying an inputsignal and outputting an amplified signal (e.g., an amplified RF analogsignal). For example, gain component 370 may include a power amplifier,a variable gain component, and/or the like. In some aspects, gaincomponent 370 may have variable gain control. The gain component 370 mayconnect to oscillator 360 and a Tx antenna array (e.g., an antenna array310) such that an RF analog signal, provided by oscillator 360, can beamplified by gain component 370 and output to the Tx antenna array fortransmission. In some aspects, the level of amplification of gaincomponent 370 may be controlled by controller 330.

Switch 380 includes one or more components capable of enabling repeater300 to operate either to relay a signal received via an Rx antenna array(e.g., an antenna array 310) or to transmit an RF analog signalgenerated by repeater 300 (e.g., an RF analog signal generated byoscillator 360 and amplified by gain component 370). In some aspects,the position of switch 380 may be controlled by the controller 330.

In some aspects, one or more antenna arrays 310, gain component 320,controller 330, communication component 340, MUX/DEMUX 350, oscillator360, gain component 370, switch 380, and/or the like may perform one ormore techniques associated with in-band configuration of a repeater, asdescribed in more detail elsewhere herein. For example, one or morecomponents of repeater 300 may perform or direct operations of, forexample, process 700 of FIG. 7 and/or other processes as describedherein.

In some aspects, repeater 300 may include means for receiving, in a BWPthat carries a control interface of a repeater, an indication of arepeater configuration for the repeater, means for communicating, basedat least in part on the repeater configuration, with at least one of aBS or a UE, and/or the like. In some aspects, such means may include oneor more components of repeater 300 described in connection with FIG. 3 ,such as antenna array 310, gain component 320, controller 330,communication component 340, MUX/DEMUX 350, oscillator 360, gaincomponent 370, and/or switch 380.

As indicated above, FIG. 3 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 3 . For example,repeater 300 may include additional components, fewer components,different components, or differently arranged components than thoseshown in FIG. 3 . Furthermore, two or more components shown in FIG. 3may be implemented within a single component, or a single componentshown in FIG. 3 may be implemented as multiple components. Additionally,or alternatively, a set of components (e.g., one or more components) ofrepeater 300 may perform one or more functions described as beingperformed by another set of components of repeater 300.

FIG. 4 is a diagram illustrating examples 400 of radio access networks,in accordance with various aspects of the disclosure.

As shown by reference number 405, a traditional (e.g., 3G, 4G, LTE,and/or the like) radio access network may include multiple BSs 410(e.g., access nodes (AN)), where each BS 410 communicates with a corenetwork via a wired backhaul link 415, such as a fiber connection. A BS410 may communicate with a UE 420 via an access link 425, which may be awireless link. In some aspects, a BS 410 shown in FIG. 4 may correspondto a BS 110 shown in FIG. 1 . Similarly, a UE 420 shown in FIG. 4 maycorrespond to a UE 120 shown in FIG. 1 .

As shown by reference number 430, a radio access network may include awireless backhaul network, sometimes referred to as an integrated accessand backhaul (IAB) network. In an IAB network, at least one BS is ananchor BS 435 that communicates with a core network via a wired backhaullink 440, such as a fiber connection. An anchor BS 435 may also bereferred to as an IAB donor (or IAB-donor). The IAB network may includeone or more non-anchor BSs 445, sometimes referred to as relay BSs orIAB nodes (or IAB-nodes). The non-anchor BS 445 may communicate directlywith or indirectly with (e.g., via one or more other non-anchor BSs 445)the anchor BS 435 via one or more backhaul links 450 to form a backhaulpath to the core network for carrying backhaul traffic. Backhaul link450 may be a wireless link. Anchor BS(s) 435 and/or non-anchor BS(s) 445may communicate with one or more UEs 455 via access links 460, which maybe wireless links for carrying access traffic. In some aspects, ananchor BS 435 and/or a non-anchor BS 445 shown in FIG. 4 may correspondto a BS 110 shown in FIG. 1 . Similarly, a UE 455 shown in FIG. 4 maycorrespond to a UE 120 shown in FIG. 1 .

As shown by reference number 465, in some aspects, a radio accessnetwork that includes an IAB network may utilize millimeter wavetechnology and/or directional communications (e.g., beamforming,precoding, and/or the like) for communications between BSs and/or UEs(e.g., between two BSs, between two UEs, and/or between a BS and a UE).For example, wireless backhaul links 470 between BSs may use millimeterwaves to carry information and/or may be directed toward a target BSusing beamforming, precoding, and/or the like. Similarly, the wirelessaccess links 475 between a UE and a BS may use millimeter waves and/ormay be directed toward a target wireless node (e.g., a UE and/or a BS).In this way, inter-link interference may be reduced.

In some aspects, an IAB network may support a multi-hop network and/or amulti-hop wireless backhaul. Additionally, or alternatively, each nodeof an IAB network may use the same radio access technology (e.g.,5G/NR). Additionally, or alternatively, nodes of an IAB network mayshare resources for access links and backhaul links, such as timeresources, frequency resources, spatial resources, and/or the like.Furthermore, various architectures of IAB nodes and/or IAB donors may besupported. In some aspects, an IAB donor may include a central unit (CU)that configures IAB nodes that access a core network via the IAB donor,and may include a distributed unit (DU) that schedules and communicateswith child nodes of the IAB donor. An IAB node may include a mobileterminal (MT) that is scheduled by and communicates with a DU of aparent node, and may include a DU that schedules and communicates withchild nodes of the IAB donor. A DU of a node may perform functionsdescribed herein in connection with BS 110 for that node, and an MT of anode may perform functions described herein in connection with UE 120for that node.

In some aspects, propagation distances in an IAB network or another typeof wireless communication network can be improved by using a repeater140. For example, a repeater 140 may forward signals between a UE and aBS, an IAB donor, or an IAB node. As another example, a repeater 140 ayforward signals between IAB donors, between an IAB donor and an IABnode, and/or the like. In some aspects, “backhaul link” may refer to alink between a BS and a repeater 140, and “access link” may refer to alink between a repeater 140 and a UE.

As indicated above, FIG. 4 is provided as an example. Other examples maydiffer from what is described with regard to FIG. 4 .

FIGS. 5A-5C are diagrams illustrating examples 500 of communicationusing a repeater, in accordance with various aspects of the presentdisclosure.

Because millimeter wave communications have a higher frequency andshorter wavelength than other types of radio waves used forcommunications (e.g., sub-6 GHz communications), millimeter wavecommunications may have shorter propagation distances and may be moreeasily blocked by obstructions than other types of radio waves. Forexample, a wireless communication that uses sub-6 GHz radio waves may becapable of penetrating a wall of a building or a structure to providecoverage to an area on an opposite side of the wall from a BS 110 thatcommunicates using the sub-6 GHz radio waves. However, a millimeter wavemay not be capable of penetrating the same wall (e.g., depending on athickness of the wall, a material from which the wall is constructed,and/or the like). Some techniques and apparatuses described herein use arepeater 140 to increase the coverage area of a BS 110 (e.g., a BS 110that communicates using millimeter wave communications and/or othertypes of communications), to extend coverage to UEs 120 without line ofsight to the BS 110 (e.g., due to an obstruction), and/or the like.

For example, as illustrated in the example of FIG. 5A, an obstructionbetween a UE and a BS blocks or otherwise reduces the quality of a linkbetween the BS and the UE. However, no obstructions or fewerobstructions exist between a repeater and the UE and, as a result, it ispossible that communications between the repeater and the UE will have ahigher quality than communications directly between the BS the UE.

As further shown in FIG. 5A, the repeater may perform directionalcommunication by using beamforming to communicate with the BS via afirst beam pair (e.g., a backhaul beam pair over a backhaul link) and tocommunicate with the UE via a second beam pair (e.g., an access beampair over an access link). “Beam pair” may refer to a transmit (Tx) beamused by a first device for transmission and a receive (Rx) beam used bya second device for reception of information transmitted by the firstdevice via the Tx beam.

As shown in FIG. 5B, the repeater may relay or forward downlinkcommunications by transmitting RF analog signals received from the BSvia an Rx beam of the first beam pair to the UE using a Tx beam of thesecond beam pair. In some aspects, the combination of the Rx beam of thefirst beam pair and the Tx beam of the second beam pair may be referredto as a downlink path.

As used herein, relaying or forwarding a received RF analog signal mayrefer to transmitting the received RF analog signal (e.g., afteramplifying the received RF analog signal) without decoding the receivedRF analog signal and/or without modifying information carried in thereceived RF analog signal. Alternatively, relaying or forwarding areceived RF analog signal may refer to transmitting the received RFanalog signal after decoding the received signal and/or modifyinginformation carried in the received RF analog signal. In some aspects, areceived RF analog signal may be relayed or forwarded using a differenttime resource, a different frequency resource, and/or a differentspatial resource (e.g., a different beam) to transmit the RF analogsignal as compared to a time resource, a frequency resource, and/or aspatial resource in which the RF analog signal was received.

As shown in FIG. 5C, the repeater may relay or forward uplinkcommunications by transmitting RF analog signals received from the UEvia an Rx beam of the second beam pair to the BS using an Rx beam of thefirst beam pair. In some aspects, the combination of the Tx beam of thefirst beam pair and the Rx beam of the second beam pair may be referredto as an uplink path.

As indicated above, FIGS. 5A-5C are provided as examples. Other examplesmay differ from what is described with regard to FIGS. 5A-5C.

As indicated above, a repeater (e.g., a repeater 140, a repeater 300,and/or the like) may be capable of receiving and relaying or forwardingan RF analog signal from a BS (e.g., a BS 110) and a UE (e.g., UE 120).However, to reduce the cost and complexity of the repeater and/or toreduce the cost and complexity of deploying the repeater in a wirelessnetwork, the repeater may not be equipped and/or configured withhardware and/or software that would otherwise permit the repeater totrack, monitor, and/or otherwise manage the access link andcorresponding beam pair associated with a UE with which the repeatercommunicates. As a result, the repeater may generally not be capable ofdetermining which beams to use for communication with the UE, may not becapable of determining when the repeater is to be active for forwardingcommunications between the BS and the UE, may not be capable ofdetermining when the repeater may operate in an idle or low-power mode(e.g., by powering off particular components and/or interfaces of therepeater), and/or the like. This may cause reduced operating efficiencyof the repeater. For example, the repeater may consume processing,memory, and/or power resources when the repeater should be in an idle orlow-power mode, the repeater may operate using suboptimal beams forcommunicating with the BS and/or the UE, and/or the like.

Some aspects described herein provide techniques and apparatusesassociated with in-band repeater control. In some aspects, a BS mayconfigure a repeater configuration, based at least in part on which arepeater (e.g., a repeater 140, a repeater 300, and/or the like) maycommunicate with a BS and/or a UE by relaying or forwarding RF analogsignals between the BS and the UE. The BS may transmit an indication ofthe repeater configuration to the repeater by in-band control signaling.For example, the BS may transmit the indication of the repeaterconfiguration on a control interface associated with the repeater, andthe control interface may be carried in a BWP that is included in anoperating frequency bandwidth of the repeater.

The BWP includes a contiguous set of physical resource blocks of theoperating frequency bandwidth that is active and used by the repeater toforward communications between other wireless communication devices(e.g., UEs, BSs, and/or the like). The control interface may be acommunication interface between the UE and the BS that is configured tocarry control signaling and/or control communications between the UE andthe BS. The control interface is included in at least a portion of thecontiguous set of physical resource blocks of the BWP. Accordingly, theindication of the repeater configuration is an in-band repeaterconfiguration in that the indication of the repeater configuration istransmitted within the BWP (e.g., within the control interface). In thisway, the indication of the repeater configuration may be transmitted tothe repeater without the need for the repeater to activate and usingadditional frequency resources outside of the BWP, which reduces memoryresource, processing resource consumption, power consumption, and/orradio resource consumption for the repeater.

Moreover, transmitting the repeater configuration to the repeater on thecontrol interface in the BWP enables the BS to configure efficientoperation of the repeater while permitting less complex repeaters to bedeployed in a wireless network. For example, the BS may use the repeaterconfiguration to indicate, to the repeater, one or more time durationsduring which the repeater may communicate with the BS and/or the UE, mayindicate whether the repeater is to operate in an idle or low-power mode(e.g., by powering on or off particular components of the repeater), mayindicate whether the repeater is to activate an uplink path and/ordownlink path between the BS and the UE, may indicate one or morebeamforming parameters, and/or other parameters. In this way, therepeater is enabled to receive the in-band communication from the BS,and is enabled to operate according parameters that are optimallyselected for the repeater in the repeater configuration.

FIGS. 6A-6E are diagrams illustrating examples 600 of in-band repeatercontrol, in accordance with various aspects of the present disclosure.As shown in FIGS. 6A-6E, examples 600 may include communication betweena BS (e.g., BS 110), a UE (e.g., UE 120), and a repeater (e.g., repeater140, repeater 300, and/or the like). In some aspects, the BS, the UE,and the repeater may be included in a wireless network (e.g., wirelessnetwork 100). In some aspects, the BS and/or the UE may perform one ormore techniques described in connection with FIGS. 6A-6E using one ormore components described above in connection with FIG. 2 . In someaspects, the repeater may perform one or more techniques described inconnection with FIGS. 6A-6E using one or more components described abovein connection with FIG. 3 .

As shown in FIG. 6A, and by reference number 602, to configure therepeater for communication with the BS and/or the UE, the BS maygenerate one or more repeater configurations and may transmit anindication of the one or more repeater configurations to the repeater.In some aspects, the BS may transmit and the repeater may receive anindication of the repeater configuration via a control interfaceassociated with the repeater. Moreover, the BS may transmit theindication of the repeater configuration in an in-band BWP that carriesthe control interface. In other words, the BWP may be included within anoperating frequency bandwidth of the repeater (e.g., a frequencybandwidth that the repeater uses to relay or forward RF analog signalsbetween the BS and the UE).

The BWP includes a contiguous set of physical resource blocks of theoperating frequency bandwidth that is active and used by the repeater toforward communications between other wireless communication devices(e.g., UEs, BSs, and/or the like). The control interface may be acommunication interface between the UE and the BS that is configured tocarry control signaling and/or control communications between the UE andthe BS. The control interface is included in at least a portion of thecontiguous set of physical resource blocks of the BWP. Accordingly, theindication of the repeater configuration is an in-band repeaterconfiguration in that the indication of the repeater configuration istransmitted within the BWP (e.g., within the control interface). In thisway, the indication of the repeater configuration may be transmitted tothe repeater without activating and using additional frequency resourcesoutside of the BWP.

In some aspects, the BS may direct the indication of the one or morerepeater configurations to the repeater (e.g., as opposed tocommunications that are directed to the UE) by transmitting theindication of the one or more repeater configurations to the repeaterbased at least in part on an identifier associated with the repeater.For example, the BS may scramble a signaling communication carrying theindication of the one or more repeater configurations, based at least inpart on a radio network temporary identifier (RNTI) associated with therepeater, which may be different from an RNTI or another identifierassociated with the UE. In this case, the repeater may receive theindication of the one or more repeater configurations in the signalingcommunication and may descramble the signaling communication based atleast in part on the RNTI associated with the repeater.

In some aspects, the BS may specify (e.g., in a signaling communicationidentifying the one or more repeater configurations, in anothersignaling communication, and/or the like) that the repeater is toprovide acknowledgement (ACK) or negative acknowledgement (NACK)feedback for the signaling communication identifying the one or morerepeater configurations. For example, the BS may specify that therepeater is to provide an ACK or a NACK. In this case, the repeater maytransmit an ACK to the BS if the repeater successfully receives anddecodes the signaling communication, and may transmit a NACK if therepeater cannot decode the signaling communication. As another example,the BS may specify that the repeater is to provide ACK-only feedback. Inthis case, the repeater may transmit an ACK to the BS if the repeatersuccessfully receives and decodes the signaling communication, andprovide no feedback to the BS if the repeater cannot decode thesignaling communication. As another example, the BS may specify that therepeater is to provide NACK-only feedback. In this case, the repeatermay transmit a NACK to the BS if the repeater cannot decode thesignaling communication, and provide no feedback to the BS if therepeater successfully receives and decodes the signaling communication.

In some aspects, the BS may configure a repeater configuration toidentify one or more time durations during which the repeater maycommunicate with the BS and/or the UE based at least in part on one ormore configuration parameters identified in the repeater configuration.In some aspects, the BS may configure a plurality of candidate repeaterconfigurations. Each of the candidate repeater configurations mayinclude a combination of time durations and configuration parameters. Inthis case, each candidate configuration may be row or column indexed ina table, electronic database, electronic file, a specification, and/oranother data structure. This permits the BS to transmit, to therepeater, a signaling communication that indexes into the plurality ofcandidate repeater configurations to identify the repeater configuration(e.g., by identifying a row index or column index associated with therepeater configuration).

A time duration may include one or more symbols, one or more slots, oneor more subframes, one or more radio frames, and/or other time-domainunits. In some aspects, a time duration may be indicated in a repeaterconfiguration by a starting time of the time duration and/or an explicitindication of an ending time of the time duration (e.g., by a symbolnumber, slot number, frame number, and/or the like). In some aspects, atime duration may be indicated in a repeater configuration by a startingtime and a timing offset relative to the starting time (e.g., number ofsymbols, slots, and/or other time-domain units relative to the startingtime), which may implicitly indicate the ending time.

In some aspects, the starting time of a time duration may be explicitlyindicated in a repeater configuration. For example, the repeaterconfiguration may specify a symbol number, slot number, frame number,and/or the like at which the time duration is to commence. In someaspects, the starting time of a time duration may be implicitlyindicated in the repeater configuration. For example, the repeaterconfiguration may specify a timing offset (e.g., number of symbols,slots, and/or other time-domain units) relative to a time at which thesignaling communication identifying the repeater configuration wastransmitted by the BS or received by the repeater. In this case, thetiming offset (and thus, the starting time) may be based at least inpart on a capability associated with the repeater. For example, therepeater may transmit an indication to the BS of a capability parameterassociated with the capability of the repeater to receive and process arepeater configuration. In this way, the BS may consider the hardwareand/or software capability of the repeater when configuring timedurations for a repeater configuration for the repeater.

In some aspects, the configuration parameters included in a repeaterconfiguration may include various operating mode parameters,communication path parameters, beamforming parameters, measurementparameters, reference signal parameters, and/or other types ofconfiguration parameters. In some aspects, a repeater configuration mayinclude one or more of the configuration parameters described hereinand/or other configuration parameters.

In some aspects, a repeater configuration may indicate that the repeateris to be powered on (e.g., that the repeater is to power on one or morecomponents of the repeater, such as one or more antenna arrays 310, gaincomponent 320, controller 330, communication component 340, MUX/DEMUX350, oscillator 360, gain component 370, switch 380, and/or the like)and is to operate in an active mode during a time duration indicated inthe repeater configuration. In some aspects, a repeater configurationmay indicate that the repeater is to power off one or more components ofthe repeater (e.g., one or more antenna arrays 310, gain component 320,controller 330, communication component 340, MUX/DEMUX 350, oscillator360, gain component 370, switch 380, and/or the like) such that therepeater operates in an idle, inactive, or low-power mode during a timeduration indicated in the repeater configuration.

In some aspects, a repeater configuration may indicate that the repeateris to activate an uplink path between the BS and the UE during a timeduration indicated in the repeater configuration and/or is to activate adownlink path between the BS and the UE during the time duration. Inthis case, the repeater may activate an Rx beam of a first beam pairassociated with the BS and a Tx beam of second beam pair associated withthe UE to activate the downlink path and/or may activate a Tx beam of afirst beam pair associated with the BS and an Rx beam of second beampair associated with the UE to activate the uplink path.

In some aspects, a repeater configuration may indicate a gain parameterthat the repeater is to use for relaying or forwarding RF analog signalsduring a time duration indicated in the repeater configuration. In thiscase, a controller of the repeater (e.g., controller 330) may control again component (e.g., gain component 320, gain component 370, and/or thelike) by controlling, based at least in part on the gain parameter, alevel of amplification or gain that is applied by the gain component toan input signal when generating an output signal.

In some aspects, a repeater configuration may indicate one or morebeamforming configurations, such as a transmit beamforming configurationand/or a receive beamforming configuration, that the repeater is to useduring a time duration indicated in the repeater configuration. Thetransmit beamforming configuration may identify a codebook-basedcodeword index for the Tx beam associated with the BS and/or the Tx beamassociated with the UE, one or more beamforming weights (e.g., phaseshifting coefficients, amplitude coefficients, and/or the like) that areto be applied to the Tx beam associated with the BS and/or the Tx beamassociated with the UE, adjustments to one or more beamforming weightsof the Tx beam associated with the BS and/or the Tx beam associated withthe UE (e.g., adjustments to phase shift and/or amplitude of the Tx beamassociated with the BS and/or the Tx beam associated with the UE),and/or other beamforming parameters.

Similarly, the receive beamforming configuration may identify acodebook-based codeword index for the Rx beam associated with the BSand/or the Rx beam associated with the UE, one or more beamformingweights (e.g., phase shifting coefficients, amplitude coefficients,and/or the like) that are to be applied to the Rx beam associated withthe BS and/or the Rx beam associated with the UE, adjustments to one ormore beamforming weights of the Rx beam associated with the BS and/orthe Rx beam associated with the UE (e.g., adjustments to phase shiftand/or amplitude of the Rx beam associated with the BS and/or the Rxbeam associated with the UE), and/or other beamforming parameters.

In some aspects, a repeater configuration may indicate that the repeateris to perform one or more measurements during a time duration indicatedin the repeater configuration, and may indicate that the repeater is toreport the measurement results to the BS during the time duration and/oris to store the measurement results and report the measurement resultsat another time. The one or more measurements may include one or moreRSRP measurements, one or more RSSI measurements, one or more RSRQmeasurements, one or more CQI measurements, and/or the like. Therepeater configuration may indicate that the repeater is to perform theone or more measurements for one or more uplink communications receivedfrom the UE during the time duration and/or for one or more downlinkcommunications received from the BS during the time duration.

In some aspects, a repeater configuration may indicate that the repeateris to transmit one or more reference signals to the BS and/or the UEduring a time duration indicated in the repeater configuration. The oneor more reference signals may include a channel state informationreference signal (CSI-RS), a demodulation reference signal (DMRS), asounding reference signal (SRS), and/or other types of referencesignals.

As shown in FIG. 6B, and by reference number 604, the repeater maycommunicate with the BS and/or the UE based at least in part on the oneor more repeater configurations received from the BS. In some aspects,the repeater may communicate with the BS and/or the UE based at least inpart on one or more configuration parameters, indicated in the one ormore repeater configurations, during one or more time durationsindicated in the one or more repeater configurations.

For example, the repeater may power on one or more components associatedwith the repeater and/or power off one or more components associatedwith the repeater during a time duration indicated in a repeaterconfiguration based at least in part on an indication in the repeaterconfiguration to power on the one or more components and/or power offthe one or more components.

As another example, if a repeater configuration indicates that therepeater is to activate an uplink path between the BS and the UE and/ora downlink path between the BS and the UE during a time durationindicated by the repeater configuration, the repeater configuration mayactivate one or more Tx beams and/or Rx beams to activate the uplinkpath and/or the downlink path. In some aspects, the repeater maycommunicate with the BS and/or the UE via the uplink path by receiving,on an Rx beam, an RF analog signal carrying an uplink communication fromthe UE and relaying or forwarding the RF analog signal to the BS on a Txbeam. In some aspects, the repeater may communicate with the BS and/orthe UE on the downlink path by receiving, on an Rx beam, an RF analogsignal carrying a downlink communication from the BS and relaying orforwarding the RF analog signal to the UE on a Tx beam.

As another example, if a repeater configuration includes a receivebeamforming configuration, the repeater may configure one or more Rxbeams based at least in part on the one or more configuration parametersidentified in the receive beamforming configuration and receive one ormore communications (e.g., uplink communications and/or downlinkcommunications) via the configured one or more Rx beams. As anotherexample, if a repeater configuration includes a transmit beamformingconfiguration, the repeater may configure one or more Tx beams based atleast in part on the one or more configuration parameters identified inthe transmit beamforming configuration, and receive one or morecommunications (e.g., uplink communications and/or downlinkcommunications) via the configured one or more Tx beams.

As another example, if a repeater configuration indicates that therepeater is to perform one or more measurements during a time durationindicated in the repeater configuration, the repeater may perform theone or more measurements for one or more uplink communications receivedfrom the UE and/or one or more downlink communications received from theBS during the time duration. As another example, if a repeaterconfiguration indicates that the repeater is to transmit one or morereference signals during a time duration indicated in the repeaterconfiguration, the repeater may transmit the one or more referencesignals to the BS and/or the UE during the time duration.

As another example, if a repeater configuration indicates a gainparameter that is to be used during a time duration indicated in therepeater configuration, the repeater may relay or forward an uplinkcommunication during the time duration by amplifying the received RFanalog signal carrying the uplink communication based at least in parton the gain parameter, and/or may relay or forward a downlinkcommunication during the time duration by amplifying the received RFanalog signal carrying the downlink communication based at least in parton the gain parameter.

FIGS. 6C-6E illustrate various example repeater configurations. In someaspects, the example repeater configurations may be implemented asseparate repeater configurations, may be combined into a single repeaterconfiguration, may be used to configure a repeater with a combination ofa plurality of repeater configurations, and/or the like. Moreover, otherrepeater configurations may be configured and/or combined for use by therepeater. As shown in FIG. 6C, in some aspects, an example repeaterconfiguration may include a repeater configuration that the BS transmitsto the repeater in a downlink control information (DCI) communication.In some aspects, the example repeater configuration may indicate thatthe repeater is to communicate with the BS and/or the UE via an uplinkpath and/or a downlink path using one or more Tx and/or Rx beams.

As further shown in FIG. 6C, in some aspects, the DCI communicationcarrying the repeater configuration may be transmitted by the BS orreceived by the repeater at a time T₀. In some aspects, the examplerepeater configuration may indicate a starting time (T-Start) of a timeduration during which the repeater is to communicate with the BS and/orthe UE based at least in part on one or more configuration parametersindicated in the repeater configuration. For example, the examplerepeater configuration may explicitly specify T-Start or implicitlyspecify T-Start by specifying a timing offset (T_(SΔ)) relative to T₀.Moreover, the example repeater configuration may indicate an ending time(T-End) of the time duration. For example, the example repeaterconfiguration may explicitly specify T-End or implicitly specify T-Endby specifying a timing offset (T_(EΔ)) relative to T-Start.

As shown in FIG. 6D, in some aspects, an example repeater configurationmay include a plurality of repeater configurations that the BS transmitsto the repeater in a DCI communication. In some aspects, each of theplurality of example repeater configurations may indicate that therepeater is to communicate with the BS and/or the UE via an uplink pathand/or a downlink path using one or more Tx and/or Rx beams. Forexample, an example downlink repeater configuration may indicate thatthe repeater is to perform downlink communication with the BS and the UEvia a downlink path using an Rx beam configured to communicate with theBS and a Tx beam configured to communicate with the UE. As anotherexample, an example uplink repeater configuration may indicate that therepeater is to perform uplink communication with the BS and the UE viaan uplink path using a Tx beam configured to communicate with the BS andan Rx beam configured to communicate with the UE.

As further shown in FIG. 6D, in some aspects, the DCI communicationcarrying the plurality of example repeater configurations may betransmitted by the BS or received by the repeater at a time T₀. Theexample downlink repeater configuration may indicate a starting time(T₁-Start) of a first time duration during which the repeater is tocommunicate with the BS and/or the UE based at least in part on one ormore configuration parameters indicated in the example downlink repeaterconfiguration. For example, the example downlink repeater configurationmay explicitly specify T₁-Start or implicitly specify T₁-Start byspecifying a timing offset relative to T₀. Moreover, the exampledownlink repeater configuration may indicate an ending time (T₁-End) ofthe first time duration. For example, the example downlink repeaterconfiguration may explicitly specify T₁-End or implicitly specify T₁-Endby specifying a timing offset relative to T₁-Start.

The example uplink repeater configuration may indicate a starting time(T₂-Start) of a second time duration during which the repeater is tocommunicate with the BS and/or the UE based at least in part on one ormore configuration parameters indicated in the example uplink repeaterconfiguration. For example, the example uplink repeater configurationmay explicitly specify T₂-Start or implicitly specify T₂-Start byspecifying a timing offset relative to T₀, T₁-End, and/or the like.Moreover, the example uplink repeater configuration may indicate anending time (T₂-End) of the second time duration. For example, theexample uplink repeater configuration may explicitly specify T₂-End orimplicitly specify T₂-End by specifying a timing offset relative toT₂-Start. In some aspects, the BS may configure the first time durationand the second time duration such that the first time duration and thesecond time duration are non-overlapping.

As shown in FIG. 6E, in some aspects, an example repeater configurationmay include a periodic or semi-static repeater configuration that the BStransmits to the repeater in a medium access control (MAC) controlelement (MAC-CE) communication. In some aspects, the BS may transmit aperiodic or semi-static repeater configuration in a radio resourcecontrol (RRC) communication. In some aspects, the example periodic orsemi-static repeater configuration may indicate that the repeater is tocommunicate with the BS and/or the UE via an uplink path and/or adownlink path using one or more Tx and/or Rx beams.

As further shown in FIG. 6E, in some aspects, the MAC-CE communicationcarrying the example periodic or semi-static repeater configuration maybe transmitted by the BS or received by the repeater at a time T₀. Theexample periodic or semi-static repeater configuration may indicate astarting time (T-Start) of a time duration during which the repeater isto communicate with the BS and/or the UE based at least in part on oneor more configuration parameters indicated in the example periodic orsemi-static repeater configuration. For example, the example periodic orsemi-static repeater configuration may explicitly specify T-Start orimplicitly specify T-Start by specifying a timing offset (T_(SΔ))relative to T₀. Moreover, the example periodic or semi-static repeaterconfiguration may indicate an ending time (T-End) of the time duration.For example, the example periodic or semi-static repeater configurationmay explicitly specify T-End or implicitly specify T-End by specifying atiming offset (T_(EΔ)) relative to T-Start. Moreover, the exampleperiodic or semi-static repeater configuration may indicate that therepeater is to communicate with the BS and/or the UE across a pluralityof periodically or semi-statically scheduled time durations based atleast in part on the one or more configuration parameters indicated inthe example periodic or semi-static repeater configuration.

In this way, the BS may configure one or more repeater configurations,based at least in part on which the repeater may communicate with the BSand/or the UE by relaying or forwarding RF analog signals (e.g., RFanalog signals carrying uplink communications and/or downlinkcommunications) between the BS and the UE. The BS may transmit anindication of the repeater configuration to the repeater by in-bandcontrol signaling. For example, the BS may transmit the indication ofthe repeater configuration on a control interface associated with therepeater, and the control interface may be carried in a BWP that isincluded in an operating frequency bandwidth of the repeater. In thisway, the repeater configuration permits efficient operation of therepeater while permitting the reduced costs and complexities of therepeater and/or of deploying the repeater in a wireless network.

As indicated above, FIGS. 6A-6E are provided as examples. Other examplesmay differ from what is described with respect to FIGS. 6A-6E.
